Now I see what happens! latexsym.sty uses the lasy font for \Diamond, but as
lucidabr.sty redefines \Diamond and makes it the same as \lozenge

372 \DeclareMathSymbol{\Diamond}{\mathord}{arrows}{8}
...
540 \DeclareMathSymbol{\lozenge}{\mathord}{arrows}{8}

then \Diamond is taken from Lucida fonts, but if you call latexsym.sty
*after* lucidabr.sty, everything works OK.

In the following example comment out and uncomment \usepackage{latexsym} and
you'll see the change:

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage{textcomp}
\usepackage{lucidabr}
\usepackage{amssymb}
\usepackage{latexsym}
\begin{document}

\( \Box \quad \square \qquad \Diamond \quad \lozenge \)

$\Box$

$\square$

$\Diamond$

$\lozenge$

\end{document}


Best,
